Electron Wrapper for Java Web Apps

Wrap an existing Java Web Application with Electron without touching your code.

Uses

1. Node JS
2. Electron
3. Java VM

Try it!

Preparations

1. Download and install npm from https://nodejs.org/en/download/
2. By default the Java web application is required to run on localhost:8080 (configure if otherwise under electron-src\main.js:78).
3. By default java needs to be available via the path variable (configure if otherwise the path in the main.js)
4. The provided Jar needs to be executable via java -jar <file>.jar.
5. Place your built (Fat-)Jar in the jar folder.

Features

• Starts a (Fat-)Jar
• Shows during f.e. Servlet Container startup a loading Animation (can be replaced)

What can be customized?

Basically everything but you will need to rebuilt the application most of the time f.e.:

• Logging (under .\electron-src\main.js:74)
• Loading animation (under .\electron-src\ replace the loading.html file)
• Loading animation window size (under .\electron-src\main.js:58-59)
• Application icon (under .\electron-src\ replace the icon.ico file)
• Main window title (under .\electron-src\main.js:103)
• Main window size (under .\electron-src\main.js:104-105)
• Special run parameters to be passed to the jar (under electron-src\main.js:67)

Running debug version

Windows

> electron-app-debug.bat

Unix

> ./electron-app-debug.sh

Build application for host arch

Windows

> electron-app-package.bat

Application will be bundled to output/electron-vaadin-... (pending on the system you compile on)

Unix

> ./electron-app-package.sh

Application will be bundled to output/electron-vaadin-... (pending on the system you compile on)

Build application for all archs (Window 32 + 64 Bit, Darwin ...)

Windows

> electron-app-package-all.bat

Application will be bundled multiple times for all archs output/electron-vaadin-...

Unix

> ./electron-app-package-all.sh

Application will be bundled multiple times for all archs output/electron-vaadin-...
